Data generating process when $x's$ and $u$ are not correlated¶
Our population regression equation is of the from
$$ y = 2 - 3x_1 + 4x_2 + u$$Let's take samples of our population and estimate $\beta's$ many times to prove that $\beta's$ sampling distribution is centered on the true value.
From our samples we will run a regression $$ y = \hat\beta_0 + \hat\beta_1 x_1 + \hat\beta_2x_2 + \hat{u} $$ When $x's$ and $u$ are not correlated the variance covariance matrix looks like:
\begin{equation*} \Sigma^2 = \begin{bmatrix} \sigma_{x_{1}}^2 & 0 & 0 \\ 0 & \sigma_{x_{2}}^2 & 0 \\ 0 & 0 & \sigma_{u}^2 \end{bmatrix} = \begin{bmatrix} 4 & 0 & 0 \\ 0 & 16 & 0 \\ 0 & 0 & 16 \end{bmatrix} \end{equation*}Properties of the $\beta's$¶
Now, using numpy, simulate some data where u is not correlated to x, and put it in a pandas data frame. This corresponds to the DGP:
Population model
$$y = 2 -3x_1 + 4x_2 + u$$

Let's do the task that we have to repeat once and think about how to do it many times:
- Take a sample, find $\hat{\beta}$.
In [67]:
# Draw a random sample of 1,000 observations from the population data.
#Estimate the parameters β_0, β_1 and β_2.
s = data.sample(n=1000, random_state=1)
reg=smf.ols(formula='y ~ x1 + x2', data=s)
reg = reg.fit()

Notes:
[1] Standard Errors assume that the covariance matrix of the errors is correctly specified.
Repeat the process:
- take many random samples, find $\hat{\beta}$, and store them:
In [68]:
# set the number of iterations
samples = 5000
# set the beta vectors
beta0_ar = []
beta1_ar = []
beta2_ar = []
# use a loop for repetitions
for i in range(samples):
s = data.sample(n=500, random_state=i)
reg=smf.ols(formula='y ~ x1 + x2', data=s).fit()
beta0_ar.append(reg.params[0])
beta1_ar.append(reg.params[1])
beta2_ar.append(reg.params[2])
coefs = pd.DataFrame({'beta0': beta0_ar, 'beta1': beta1_ar, 'beta2': beta2_ar})

Using lists comprehensions¶
The use of lists in python allows us to store all the regression results in a single object.
Comprehensions are ways to populate lists applying a function iteratively
In [71]:
# use the iteration object
samples = 5000
# create the function to iterate
def reg_f(N,rs,formula, dato):
s = dato.sample(n=500, random_state=rs)
reg=smf.ols(formula=formula, data=s).fit()
return(reg)
# use the list comprehension
list_ols = {reg_f(500, i, 'y ~ x1 + x2', data) for i in range(samples)}
#We want to exteract the coefficients from the regression and put all of them into a vector
coefs =[i.params for i in list_ols]
coefs = pd.DataFrame(np.asanyarray(coefs),columns=['b0','b1','b2'])
coefs.describe()
Out[71]:
| b0 | b1 | b2 | |
|---|---|---|---|
| count | 5000.000000 | 5000.000000 | 5000.000000 |
| mean | 1.963885 | -2.997548 | 4.003105 |
| std | 0.332411 | 0.088966 | 0.045430 |
| min | 0.774054 | -3.348139 | 3.846466 |
| 25% | 1.736807 | -3.057236 | 3.972799 |
| 50% | 1.961183 | -2.997133 | 4.003168 |
| 75% | 2.189971 | -2.938729 | 4.034459 |
| max | 3.065221 | -2.692965 | 4.163186 |
Now lets use pandas.DataFrame.hist function to visualize their distributions
